This is why cleaning can cause your injury.
When you’re cleaning windows, you’re repeating the same shoulder movement over and over again, often with your arm up and away from your body.
Your rotator cuff muscles have an important job. They help keep the ball of your shoulder centred in the socket while your arm moves.
But as those muscles fatigue, they become less effective at controlling the shoulder. Now add your gym training on top of that, and you’re loading a shoulder that’s already been working for hours.
Over time, that repetitive load can contribute to problems like rotator cuff tendinopathy and impingement type shoulder pain.
That’s why we physically examine the shoulder first. We assess your rotator cuff strength, shoulder blade movement, range of motion and whether your neck is contributing.
Depending on what we find, we can use shockwave therapy on the affected tendon and specific chiropractic adjustments to improve movement through the neck and shoulder.
But you also need to change the activity that keeps loading it.
Keep your elbow closer to your body, clean smaller sections, alternate arms and take small breaks.
You can be incredibly strong in the gym and still get injured cleaning. Gym strength and repetitive occupational load are two completely different things.
